Composition (A) for dyeing keratin fibres, comprises in a suitable dyeing medium: at least one tetraazapentamethine compound (I) of formula (W1-N1=N-C(R0)=N-N2=W2); and at least one direct dye containing at least one exonuclear quaternary ammonium group. W1a cationic heteroaromatic radical of formula (II) or (III); W2a heteroaromatic radical of formula (IV) or (V); Z0radical CR2, N or a radical NR21; Z1O, S or NR9; Z2N or CR10; Z3N or CR11; Z4N or CR12; Z5N or CR13; Z6N or CR14; Z7O, S or CR15; Z8N or CR16; Z9N or CR17; Z10N or CR18; Z11N or CR19; Z12N or CR20; Z13CR6, N or NR22; R2, R6, R10, R16H, 1-4C alkyl (optionally substituted with 1-3 OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, amino, 1-2C (di)alkylamino, carboxyl or sulfonic radicals), phenyl or sulfonylamino radical; R1, R4, R5, R7, R9, R15, R21, R221-8C alkyl (optionally substituted with 1-3 OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, amino, 1-2C (di)alkylamino, carboxyl and sulfonic radicals); either R0, R3, R8, R11-R14, R17-R20H, 1-16C hydrocarbon-based chain, optionally saturated with 1-3 unsaturations and optionally substituted with 1-3 OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, amino, 1-2C (di)alkylamino, carboxyl, sulfonic, sulfonylamino or 2-4C (poly)hydroxyalkylamino or halo ( Cl, F or Br), phenyl (optionally substituted with 1-3 OH, 1-2C alkoxy, 2-4C (poly)hydroxyalkoxy, amino, 1-2C (di)alkylamino, carboxyl, sulfonic, sulfonylamino or 2-4C (poly)hydroxy-alkylamino or halo (Cl, F or Br)), heteroaryl (pyrazolyl, pyrrolyl, imidazolyl, thiazolyl, oxazolyl, triazolyl, pyridyl, pyrimidinyl, triazinyl, pyrazinyl or pyridazinyl radicals), this hydrocarbon based chain interrupted with 1-2 O, N, S or SO2 radical (it is understood that R0, R3, R8, R11-R14, R17-R20 are peroxide bond, diazo or nitroso radicals); or R2+R10, R11+R12, R6+R16, R17+R185-6 membered carbon based aromatic ring, optionally substituted with 1-2 OH, amino, (di)(1-2C)alkylamino, 1-2C alkoxy or 2-4C (poly)hydroxyalkylamino radicals; and X : organic or mineral anion. Provided that the rings (II)-(IV) comprise not more than three N atoms and that two of the three N atoms be contiguous, the bond 5-membered cationic heteroaromatic radical (II) is linked to the N atom N1 of (I), the bond b of the 6-membered cationic heteroaromatic radical (III) is linked to the N atom N1 of (I), the double bond a1 of the 5-membered heteroaromatic radical (IV) is linked to the N atom N2 of (I), the double bond b1 of the 6-membered heteroaromatic radical (V) is linked to the N atom N2 of (I), the bond b, linking the cationic heteroaromatic radical (III) to the N atom N1 of (I) is in an ortho or para position relative to the N atom bearing the radical R4 when Z5 represents a radical CR13, the bond b is in ortho position relative to the N atom bearing the radical R4 when Z5 is N atom, the bond b1, linking the heteroaromatic radical (V) to N atom N2 of (I) is in ortho or para position relative to N bearing the radical R7 when Z11 is a radical CR19, the bond b1 is in ortho position relative to the N atom bearing the radical R7 when Z11 is N. Independent claims are included for: (1) process for dyeing keratin fibres, and in particular human keratin fibres such as the hair, comprising applying at least one dye composition (A) to the fibres to obtain the desired coloration without final rinsing or after which the fibres are rinsed, optionally washed with shampoo, rinsed again and dried; and (2) multi-compartment device or multi-compartment dyeing kit comprising: first compartment contains (A); and a second compartment comprising an oxidising agent.
